Abstract: Abstract of the Disclosure:            The technique for replacing an existing underground cable and a specific apparatus for doing so are disclosed herein. The apparatus includes a main body or cable follower which is interconnected with the cable to be replaced for slidable movement along the latter. At the same time, the apparatus provides means for reaming around the cable, preferrably by means of one or more fluid jets.  Once the soil surrounding the cable has been loosened using this apparatus, the cable can be easily pulled out of the ground.  At the same time, the replacement cable can be attached to the existing cable and pulled into its place.

Abstract: WELDING PROCESS          ABSTRACT OF THE DISCLOSURE       A welding machine lays down its welding bead at the juncture of two surfaces, back of which a pressure boundary has been formed.  A depression, or groove, is provided at the juncture of the two surfaces.  The weld bead bridges over the groove to form a junction of the two surfaces, leaving the bottom of the groove above the pressure boundary to function as a passage for materials at the surfaces which vaporize at the temperature of the welding operation.  The escape of the gases through the passage obviates the gases bubbling up through, and deteriorating, the solidifying weld material forming the junction.

Abstract: ELECTRONIC HUMIDITY CONTROL                   Abstract A control system for a humidifier, associated with a hot air furnace, that attains a high level of relative humid-ity without causing any condensation on the building interior by varying the level of operation of the humidifier as a func-tion of the rate of heat loss from the building.  Since the duty cycle of the furnace is a function of the rate of the heat loss, the system generates a digital signal related to the duty cycle and uses that signal to interrogate a digital memory storing a program of desired humidities for various duty cycles to output an instantaneous desired humidity signal which is compared with a measured humidity signal to develop an on/off control signal for the humidifier.

Abstract: ELECTRICAL MEASURING INSTRUMENT        Abstract A modular analog/digital display for use in a cylindrical aircraft instrument housing is designed to enable the digital components to be assembled without interference to the analog meter mechanism.  The digital display is of the leadless type and is clamped under compression to a circular circuit board with a pair of contact strips in registration with contacts formed on the circuit board and digital display.          The design also features a screw-on dial pointer which facilitates the assembly of the digital display components and dial to the analog meter mechanism without interference.  The pointer includes an externally threaded shaft attached at right angles thereto and a locknut threaded over the threaded pointer shaft.  An internally threaded bushing is fastened within one end of the hollow meter shaft.  An analog dial, having a central opening for accommodating the meter shaft, is slipped over the meter shaft and mounted to the meter mechanism housing or other components.  The pointer shaft is then screwed into the bushing, which acts to stiffen the thin-walled shaft, until the pointer is at a desired angular position and distance relative to the dial.  The locknut is turned until it is seated on the bushing to secure the pointer at the desired position.

Abstract: : 10 :                ABSTRACT OF THE DISCLOSURE    A method of making an arc tube for a discharge is disclosed together with sealing compositions used in the method.  The method consists of assembling together an incompletely fired or green state end closure member (complete with electrode etc.) and an arc tube also in the incompletely fired or green state.  Applying a sealing composition selected from the disclosed range and firing this assembly so that the end closure member forms a hermetic seal with the arc tube.  Separate steps for producing a completely fired end closure and arc tube and the subsequent step of sealing these two items together is thus avoided.  A ternary phase diagram defining preferred compositions is disclosed.

Abstract: POLYURETHANE FOAMS SUITABLE FOR HIGH FREQUENCY   WELDING AND PROCESS FOR PRODUCING THE SAME        ABSTRACT OF THE DISCLOSURE This invention relates to polyurethane foams capable of being welded by high frequency welding and a process for producing the same, characterized by the addition of certain ammonium salts of acids containing phosphorus to the starting components for the polyurethane foam in order that the polyurethane starting materials and the polyurethanes contain from 0.1 to 10%, by weight, of ammonium salts of phosphorus-containing acids. Phosphorus-containing ammonium salts which are available in the liquid form and completely soluble in polyols are particularly suitable with salts of phosphoric acid mono- and dibutyl esters, dialkyl phosphinic acids, alkyl phosphonic acids and alkyl phosphonic acid mono-methyl esters being preferred.  The addition of these acids significantly increases the dielectric loss factor of thermoplastic polyurethane foams and, therefore, also considerably increases their capacity for being welded by high frequency welding.

Abstract: ABSTRACT OF THE DISCLOSURE     A microprocessor is used to control the compressor and the fan of a refrigeration system, by the coolant water agitator and the carbonator water supply pump of a carbonated beverage dispensing machine.  Water levels in the carbonator and carbonator water supply and the sizes of ice banks built up therein are monitored by interrogating signals applied to an array of sensors or probes in the carbonator and its water supply reservoir. The interrogating signals are under control of the microprocessor and are of short duration with low duty cycle to prevent any plating effects which could otherwise be caused by the probes.  The source of the interrogating signals is a low voltage AC supply necessary for components of the dispensing system, in combination with a rectifier and smoothing capacitor together with a clipping diode and a voltage dropping resistor.  The microprocessor causes the resistor to be grounded repetitively to generate a square wave voltage signal thereacross.  This square wave signal is capacitively coupled to the probes to block any DC component and to apply the balanced AC interrogating signals to the probes.

Abstract: ABSTRACT            A  self-raising post of a plastic material, such as PVC, for use as a roadside marking post, a traffic sign post, a  lamp post,   or   for  other  comparable  uses  in  road  traffic environments, has  a  channel-shaped  bending  zone  with  a substantially arcuate cross section and with the convex side facing the on-coming traffic. The  cross-sectional  area  of the  bending  zone increases progressively towards the lower end, whereby the flaring-out zone (14) formed  upon  bending of the post will be larger below than above the line (11) of bending. The greater inherent  resiliency  of  the  material below  than above the line of bending will cause the post to bend back into an upright position after having been hit  by a vehicle.     Certain   embodiments  of  the  posts  are  manufactured  by diagonally  splitting  lengths  (15)  of   extrusion-moulded plastic  tubing,  forming  two identically shaped posts from each tube length.

Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed herein an acoustic or ultra-sonic power meter which includes a liquid crystal cell for detecting acoustic energy and a control circuit for applying an electric field to said cell.  The liquid crystal cell includes a liquid crystal material having elongated molecules.  The preferred liquid crystal is in the form of a layer of the nematic type which is homeo-tropically aligned.  The elongated liquid crystal mole-cules exhibit positive dielectric anisotropy wherein the dielectric constant parallel to the molecule's axis is greater than the dielectric constant perpendicular to the molecule's axis.  In the unexcited condition, the nematic layer is dark.  In the ultrasonically excited condition, the nematic layer exhibits birefringence. A restoring electric force can be applied to the liquid crystal material to suppress the acoustically-induced birefringence condition of the cell to the dark appear-ance associated with the unexcited condition.  The strength of the electric field required to suppress the birefringence is proportional to the acoustic intensity of the ultrasonic beam or acoustic field applied to the cell.
